Below is a list of the things I was going to address today. Didn't get #5 done yet... Fuel pressure could possibly be an issue, but I don't know if my gauge is 100% accurate. I tried to rent one to compare pressures, but Autozone was out of stock at all 4 locations near me.
1. Better video so exhaust can be heard and engine can be seen.

2. Double check PCM C1 blue pins 20 and 57 to constant +12V.
DONE
3. Check fuel pressure.
KOEO = 54PSI, KOER = 44PSI at idle and 54PSI when throttled moderately. Also disconnected vacuum line while running and it came up to 53PSI from from 44PSI.
4. Verify that all of the spark plug wires are firmly snapped into the coil packs? Two clicks total for factory wires.
Aftermarket wires, but verified coil pack side and plug side are all fully seated.
5. Clean out any gunk in and around the throttle blade, including pushing it open with your finger and cleaning any residue around the blade and hinge areas?
